Collect whole blood in a purple top (EDTA) tube (preferred). Extracted DNA and saliva are also acceptable.
Specimen Preparation
Please provide detailed clinical history and features. For more information contact the lab at 6-1447 or by sending an email to DGDGeneticCounselor@chop.edu.
Unacceptable Conditions
Heparinized specimens, severely hemolyzed specimens, frozen, clotted or possibly commingled specimens, blood in non-sterile or leaky containers, mislabeled or inappropriately labeled specimens.
Storage/Transport Temperature
For CHOP Phlebotomy: Samples can be collected throughout the week. Samples collected on weekends or holidays are held in Central Labs and sent to the Genomic Diagnostic Lab the following business day.
For External Clients: Refrigerate sample until shipment. Send the sample at room temperature with overnight delivery for receipt Monday through Friday, optimally within 24 hours of collection.
Please contact the lab (267-426-1447) with questions regarding non-blood specimens.
Volume Required
2-3 mL of blood or 3 ug of DNA with a concentration of at least 50 ng/ul
Minimum Required
1 mL of whole blood
Phlebotomy Draw
Yes
Clinical Features
The Hereditary Leukemia/Lymphoma Panel analyzes genes associated with cancer predisposition, particularly to leukemia/lymphoma.
Performing Lab
Division of Genomic Diagnostics
Performed
Monday-Friday 9:00am - 4:00pm
Reported
28 days
Detection Rate
The clinical sensitivity for comprehensive sequencing and copy number analysis is dependent on the patient's clinical features.
Utility
The clinical utility of the assay is to support a clinical diagnosis of the disease, facilitate genetic counseling, and assess the risk to other first degree relatives and to facilitate testing of at-risk family members.
Genomic DNA was extracted from patient tissue following standard DNA extraction protocols. Whole genome sequencing was performed on the Illumina NovaSeq 6000 platform using the Illumina DNA PCR-Free Library Prep with 150bp paired-end reads. Mapping and analysis were based on the GRCh38 reference sequence. Sequencing data was processed using the Dragen pipeline (Illumina) to call both sequence and copy number variants.
Molecular Testing Notes
The Hereditary Leukemia/Lymphoma Panel includes sequence and copy number analyses of the following genes: ATM, BRCA1, BRCA2, BRIP1, CBL*, CEBPA, CHEK2, DDX41, ETV6, FAS, G6PC3, GATA2, HAX1, HFE, IKZF1, ITK, KRAS*, MPL, NBN, NF1, PALB2, PAX5, PTPN11*, RUNX1, SBDS, SH2B3, SH2D1A, STAT3, TERT, TP53, WAS
* Sequence analysis only is performed for these genes
